BPW · THE QUALITY FACTOR / ECO Plus warranty
No chance for rust and stone impact. Optimum corrosion protection for all BPW components. Running gear from BPW offers robust technology for a long vehicle life. An important quality feature of our products is cataphoretic dip-coating with zinc-phosphating (KTLZn). This is a special surface finish that provides 5 times more effective corrosion protection than conventional painting processes. Thin layer corrosion protection processes such as Dacromet® and Geomet®, as well as chromated surface protection systems, can withstand even the hardest stone impacts.
12
Cataphoretic dip-coating with zinc-phosphating (KTLZn) provides a deep shield and meets the most exacting requirements for corrosion protection. For example, KTLZn-coated BPW components can withstand a 504-hour salt-spray mist test without any problems. BPW is also the first choice when it comes to thin-film corrosion protection processes: As well as using the familiar, tried-and-tested Dacromet® coating containing chrome VI, BPW is already adopting the EU end-of-life vehicle directive 2000/53/EC (which is at present only mandatory for vehicles up to 3.5 tonne gross weight rating) and is in some cases using chrome VI-free coating systems (e.g. Geomet®) instead of the previous systems containing chrome VI. These systems can be disposed of in an environmentally friendly way, and are not harmful to health. The result is convincing in all respects: Corrosion, cleaning chemicals and even stone impacts don’t stand a chance. And the components are ready to be installed without requiring further painting.
How it works Dacromet® and Geomet®: An inorganic, silvery coating is applied to the vehicle components using an immersion process involving an aqueous suspension of zinc and aluminium flakes. The coating is allowed to dry and then baked on at about 300 °C. KTLZn: The vehicle components are given a painstaking 10-zone pre-treatment (including zinc-phosphating), after which they are immersed in the cataphoretic dip-coating tank. A direct electric current is applied in order to coat the components with a water-soluble epoxy resin varnish. This coating is then baked on at 185 °C. Result: The best possible corrosion protection, even without a topcoat of paint.
The computer-controlled BPW cataphoretic dip-coating and zincphosphating plant represents the cutting edge in the application of corrosion protection in car production and sets the global standard for coating quality in trailer chassis and suspension systems.

BPW surface treatment – Features and benefits Wide-area corrosion protection, even on inaccessible points such as in cavities (5 times better than conventional primers and topcoat paints) Minimum rust creepage, e.g. after surface damage by stone or chipping strikes High chemical resistance, e.g. when highpressure cleaners are used with detergent additives
No further topcoat required. Where there are individual requirements for a particular lustre and colour, these finishes can be painted over using inexpensive topcoat systems without pre-treatment Hard surface: Less transport and installation damage Easier maintenance and repair procedures Fewer downtimes
Longer service life of the entire BPW chassis
High resistance to heat
Outstanding look: Surfaces without drips or runs and with an even coat thickness

Relief for tyres and the driver. For BPW, it’s purely a question of adjustment. The camber and toe-in of each BPW axle beam are set at the factory. These are minor values, but they have a big effect on driving. That is because having the right camber and toe-in adds up to greater road safety and efficiency.
Perpendicular to the carriageway Wheel centre plane Top
Top
Positive camber – Unladen vehicle Camber is defined as the angle (A) between the wheel centre plane and a line drawn perpendicular to the plane of the carriageway. The camber is positive if the top of the wheel is angled outwards when the axle is unladen.
Positive camber – Laden vehicle The bending load on the axle beam when the vehicle is laden causes the wheel to straighten. This means the tyre rolls with optimum road contact when the vehicle is laden (the most critical condition in terms of wear). This avoids uneven, premature tyre wear.

Camber and toe-in – Features and benefits Setting a positive camber ensures maximum contact between the carriageway and the tyres when the vehicle is laden, optimum tyre tracking and avoidance of uneven, premature tyre wear
26
Toe-in Toe is the angle (B) between the longitudinal axis of the vehicle and the wheel centre plane. Toe-in means the front part of the wheel is turned inwards towards the longitudinal axis of the vehicle – i.e. the distance between the front of the tyres (A) is less than the distance at the rear (B). During driving, the rolling resistance of the tyres causes the angle (B) to be forced back to zero, thereby ensuring stable straight-ahead driving. Without toe-in, the wheels would attempt to run outwards.
Having the toe-in set exactly ensures stable straight-ahead driving Lower operating costs and improved road safety

We accomplish wheels from zero to one hundred and twenty. Depending on what offset you require. BPW offers wheel hubs for wheels with and without offset, for drum or disc brakes, for single or twin tyres. Normally, wheels with 0 mm (ET 0) or 120 mm (ET 120) offset values are used on trailers and semitrailers. BPW axles for wheels with zero offset can be equipped with either drum or disc brakes. Wheels with 120 offset can only be fitted with disc brakes. Disc brakes with zero offset do not wear as much as those with 120 offset.

The BPW rigid axle can take even ultra-heavy duty transports in its stride. Whilst being a true lightweight at the same time. BPW rigid axles are the strong backbone for your trailer. They are rugged, have an extremely high load capacity and are pleasingly light. After all, with ECO Plus 2, our designers have succeeded in reducing the inherent weight of each axle by up to 25 kg. For you this means, we clear the way for greater efficiency.

Take control of costs, too. With the LL self-steering axle from BPW. The LL self-steering axle is the economic miracle of all the BPW axles. It shows off its strengths particularly when tight manoeuvring is required in delivery and distribution haulage. Thanks to its greater manoeuvrability on corners and when making turns, you benefit from more straightforward vehicle handling, less tyre wear and lower fuel consumption – over a mileage of 1 million kilometres that adds up to the impressive amounts of up to 10,000 litres of fuel and more than 40 tyres per vehicle. Just work that out for your entire fleet!

Special transports are not to be taken lightly. Unless you are driving with positive steering axles from BPW. Due to their length and the large number of axles, high-volume and high-load transporters in particular need a much larger cornering radius than conventional semitrailer units. A steering system which acts individually on all wheels – positive steering – is used to enable them to cope with normal roads all the same. Indeed, positive steering systems are a legal requirement in certain vehicle configurations.

Top of the class when it comes to difficult ground. BPW swinging axles for heavy-duty vehicles. With swinging axles, heavy-duty vehicles can master any critical road surface and heavy ground. This is because the highly flexible swinging bearings compensate ground uneveness and ensure optimum ground contact all the time providing greater safety for the driver and the payload. What is more, with swinging axles from the market leader BPW you benefit from reliable, easily maintained technology with optimised use of space and the advantages of high-volume production.

Tandem swinging axles can cope with all irregularities in the carriageway by pivoting in both the longitudinally and lateral axis of the vehicle. Single swinging axles are predominantly used in heavy-duty vehicles with several rows of axles. The lateral pivoting movement of the swinging bearings ideally complements hydraulic chassis and suspension systems.

A hydraulic axle load compensating feature ensures that axle loads remain constant in linked circuits and, depending on the vehicle concept, also offers the possibility of adjusting the level and inclination of the loading platform. As a result, safe operation is assured even under difficult road conditions and when negotiating steep loading ramps. Long vertical travel is possible in this case as well as large pivoting movements.

Not everyone wants the standard solution. So it is good to know that made-to-measure special axles are available from BPW. Wherever a normal axle system doesn’t meet the requirements – such as for box trailers as well as cable and car transporters – it is necessary to provide the customer with an individual solution. No problem, because BPW offers the right chassis and suspension products for almost every type of special vehicle. On request, we can develop a tailor-made solution that takes account of your own special requirements.
Function: The structure of an axle stub is basically the same as that in a rigid axle. However, the axle beam does not extend from side to side. It ends shortly after the brake (according to the customer’s request). The axle stub suspension which attaches the axle stub to the chassis is designed individually by the vehicle manufacturer.

the thickness of the material is reduced, the brake cylinder stroke increases, meaning that the brake camshaft has to rotate further. In this case, the function of the ECO Master slack adjuster provides an automatic adjustment. As a result, the brake cylinder stroke is always kept within the same, optimum effective area. The adjustment stroke is designed so there will always be a sufficient air gap even at higher levels of elasticity and given thermal expansion of the adjacent components (e.g. the brake drum).

Electronic safety systems for your brakes. It comes down to the right brake compatibility. Over the past few years, disc brakes and electronically controlled brake systems have become established in commercial vehicle technology. Here, systems such as ABS and EBS are leading to new possible combinations and interfaces between the towing vehicle and the trailer. Having the right brake compatibility is decisive when it comes to achieving the best braking results. The experts at BPW will be happy to advise you and recommend the optimum solution for your applications.

Further BPW recommendations and notes Strengths of disc brakes: - Very good brake force modulation - Low fading - High braking comfort (rapid response times) - Low weight Strengths of drum brakes: - Mature, robust technology - Low susceptibility to dirt because of enclosed design - Low heat transfer to the adjacent components (e.g. bearings, tyres) - Rapid brake service thanks to BPW’s patented ECO principle - Good integration into the vehicle (space) Disc brakes for zero offset wheels have a lighter system weight than 120 offset wheels, and do not wear so much since the temperature during braking is lower.
i
Wider track and spring centres are possible with 120 offset – only one spare wheel is needed for the towing vehicle and trailer, depending on the version Brake matching between the tractor unit and the trailer is essential to ensure optimum performance and a longer brake service life In general, disc brakes offer excellent braking performance. If trailers and semitrailers are towed by tractor vehicles which - do not have a secondary braking system (retarder, Intarder, engine brake, etc.) and/or - are equipped with a trailer parking brake valve (anti-jackknife brake) then the brake pad wear can be expected to be disproportionately greater than on a comparable drum brake!

The power plant for your brake system. Brake cylinders from BPW. In a brake system, it is of the utmost importance to achieve an optimum interplay between the individual components. The brake cylinders have a decisive role to play in this, because they have to provide a perfectly modulated force transfer within the brake system. BPW develops and produces its own brake cylinders for drum and disc brakes – further proof of our extensive expertise when it comes to brakes. As a system supplier, our product range includes diaphragm and spring-type cylinders.

No roads are absolutely smooth. To make up for this, we build absolutely perfect running gear. A running gear system is only ever as good as its suspension. BPW air suspension systems are individually designed to cope with where and for what they’re going to be used, and what load they’re going to carry. Only in this way it is possible to ensure the optimum driving safety at the same time as reducing the stress on the driver, the cargo and the body. This reduces wear on the tyres and cuts down the stress on the vehicle body and the cargo – as well as reducing your expenses. Another advantage: The modular construction means that it’s easy to exchange individual components in the event of a repair.

High level of driving comfort in all load conditions
The U-shaped connection comprising the axle and flexible trailing arms noticeably reduces unwanted rolling movements and reduces the load on the vehicle frame. This principle of connecting the axle and trailing arms together acts as a stabiliser to cut down rolling movements. In this way, air-sprung suspension systems from BPW achieve safe driving properties as well as a high level of driving comfort.
The trailing arm connects the axle to the vehicle frame via the air suspension hanger brackets and the air bag. BPW trailing arms (single or twin leaf springs) are highly flexible spring steel elements. They are hot-rolled from one piece, after which they are shot-peened and cataphoretic dipcoating and zinc-phosphating. Trailing arms absorb a great deal of torsional forces applied to the axle beam. Various trailing arm versions permit individual equalisation – for example for axle load, track, spring centre, centre of gravity height and driving comfort. In every situation, their stiffness and flexibility are exactly matched to the vehicle and its application. This reduces the stress on the body and ensures that the vehicle achieves a long service life. The catch plate offers the necessary safety reserves if the worst should come to the worst. Long-life steel-rubber-steel bushes (up to 4 times the service life of rubber-steel bushes) offer maintenance-free mounting of the trailing arm. The axle is exactly controlled, while tyre wear and operating costs are both reduced.

Lack of driving comfort increases the strain on the driver, the vehicle and the cargo. BPW finds the solution to this in the air. Air suspension hanger brackets transfer all control, braking and acceleration forces from the axle to the vehicle frame. Short, adjustable BPW air suspension hanger brackets with integrated shock absorber mounts make installation easier, reduce weight and cut the torsional load on the vehicle’s frame. The vehicle manufacturer benefits from straightforward cross-bracing options at the interface between the frame and the hanger bracket. Rapid unit alignment is possible using BPW hanger brackets with integrated track setting. Production tolerances on the vehicle can be equalised or wheelbases corrected without the need to unfasten the U-bolts (axle tracking). BPW air suspension hanger brackets are available in steel as well as in high-grade steel and aluminium on request. What is more, with the bolted Airlight II air suspension hanger bracket, BPW is offering manufacturers the opportunity of coating vehicle frames without air suspension hanger brackets, and not connecting them to the complete axle unit until the final assembly stage. Cold joining technology allows the bolt-on hanger bracket to be mounted on standard frames, including aluminium frames, with bottom boom width as little as 120 mm – no changes are necessary on the frame.
The shock absorber reduces vibration in the vehicle body and ensures greater driving comfort and road safety. That’s because the wheels stay in contact with the road and dynamic wheel load fluctuations are reduced. BPW uses various types of shock absorber to guarantee the best possible damping in each case. High-volume BPW shock absorbers are adapted to the vehicle, the overall height and the range of applications. The rubber bushes of BPW shock absorbers can be replaced. This is much less expensive than buying a new shock absorber.
The axle is connected to the trailing arm using the axle connection comprising: spring plates, spring pads, segments and U-bolts. Clamped, positive-locking axle connections ensure an even force transfer into the axle appropriate to the degree of load. This is only possible with square axle beams which therefore offer a long service life. The connection parts are attached at the reinforced radii of the axle beam (no welded connection). BPW uses U-bellows because of their spring characteristics. They roll over the rolling piston during compression.

Suspension / Air suspension
The air bag ensures outstanding suspension of the body and makes it possible to adjust the vehicle height using the „lifting“ and „lowering“ functions.
Air bag mounting plate
BPW air bags are firmly rolled into the mounting plate at the top at the bottom by vulwhile they are bonded onto the clamping plate canisation, which means they are guaranteed to be air-tight. The rolling is made from glass-fibre reinforced plastic with a steel support piston to give reduced weight and resistance to corrosion. The integrated bump protects against damage when the bags are vented. BPW offers stop air bags for any application (total spring travel up to 450 mm).

Suspension / Airlight Direct / Axle lift device
Axle lifts from BPW. The device for a long tyre life. As an option, multi-axle vehicles can be equipped with an axle lift to reduce the wear on the tyres when driving unladen or with a light cargo. BPW offers axle lifts for positioning in the middle or at the sides. All BPW axle lifts are compatible with the Auto-Drop system. It automatically lifts up to two axles on a tri-axle suspension (when unladen)
Suspensions
and lowers them again (when laden).
Locating the axle lift at the side is recommended for lifting the first axle and in vehicles with limited ground clearance, high axle loads or long suspension travel. The double-sided lift (for air-sprung axles up to 12 tonnes) does not need any space in front of the air suspension hanger brackets or in the middle of the vehicle. It can be fitted at any time to any axle position offering the convincing benefits of low weight and good ground clearance. Both the central axle lift device using a lifting bag and the BPW central lift with bellows fitted in the middle of the vehicle can lift one or more suspension axles and are integrated within the space of the axle unit. Their compact design means they are preferred for use in vehicles with limited ground clearance and small tyres (e.g. pallet box trailers with single tyres).

BPW PDC shock absorber. Intelligent damping that automatically detects the loading condition. The best damping, better road safety, lower maintenance costs: The BPW PDC shock absorber (PDC = Pneumatic Damping Control) improves driving properties and driving comfort because it adjusts continuously to the particular loading condition. An intelligent solution that can be OEM-fitted or retrofitted to BPW air suspension systems.
Function: The disadvantage with conventional shock absorbers is that their characteristics can only be optimally
adapted to one loading condition (usually fully laden). The PDC shock absorber detects the actual loading condition via the air suspension and adapts itself smoothly.
ticular when the trailer is empty or only partly laden. The PDC shock absorber is almost essential in high-value

vehicles and when carrying sensitive cargoes. Vehicle maintenance costs are reduced. The cargo and the carriageway
are also subjected to fewer shock loads. The PDC shock absorber is connected to the BPW air suspension system and
does not require any electronic control systems.

Suspension / PDC / 3-D trailing arms and channel crossmembers
3-D trailing arms: The ingenious „three-dimensional trailing arm“ (3-D) enables vehicle manufacturers to assamble air-sprung tri-axle suspension systems with an LL self-steering axle onto the same frame as a rigid unit without any problems – there’s no need to have a special offset frame. It goes without saying that the 3-D trailing arm offers the same functions and quality features as BPW trailing arms for rigid axles.

The channel crossmember: Vehicle manufacturers all over the world quickly appreciate the assembly benefits of this component. Whether it’s the hanger brackets, the shock absorber attachments or the crossbraces, everything is integrated to save space. Even steering axles can be connected to it without additional preparation. The channel crossmember is available in two versions – with an open, narrow hanger bracket for welding or with a cover plate for bolting/riveting onto the vehicle frame. The channel crossmember can even make additional crossmember unnecessary, depending on the frame design.

Special air suspension components from BPW. Greater efficiency for vehicle manufacturers.
No creases when you are on the move. With the Combi airbag from BPW. In road/rail/ship combined transport, trailers with vented air suspension systems are lifted by gantry cranes or manoeuvred by marshalling tractors. Conventional air suspension systems are at risk of damage to their air bags. The patented Combi airbag from BPW (European patent 0 554 573 B1) provides an effective safeguard against folding and creasing of the air bag and thereby guarantees a long service life.
Function: The air bag of a Combi airbag is divided into two parts: The air bag
is bolted onto the vehicle frame with the
rolling piston while the centring cone
is connected to the
trailing arm. When the trailer is lifted, the axle and the cone move downwards. The movement is restricted by the shock absorbers. However, the airbag remains in its rest position. When the trailer is lowered to the ground, the airbag and centring cone once more come together. The bag can neither fold nor crease. A long service life is thus assured.

The culmination of more than a century of expertise in running gear. Engineering services from BPW. BPW helps you to get your vehicle on the road in the best possible condition. With numerous engineering services that put your individual trailer requirement profile into the focus of attention. Whether FEM or brake measurements, whether driving tests or test facility trials and tilting stability calculations – our specialists advise you in detail and develop the solution that best meets your needs.
Application consulting BPW assists you in standardising vehicle frames and helps you to select axles and axle units which are appropriate for a particular market or application. With BPW, your ideas are in the best hands. That’s because BPW offers you a wide range of ingenious solutions for technical applications. Whether you have detailed questions or want to develop complete vehicles: We are happy to offer you advice. If necessary, BPW can also test vehicles in operation so as to come up with the correct solution for you based on the measured data. In this case, BPW refers to existing standards and uses its own experience, or else develops a special catalogue for you containing the necessary measures. FEM calculations BPW possesses many years of experience in performing stress measurements during driving trials. We perform computer analysis (also on the vehicle frame or frame components) and propose any necessary optimisation measures. In this way, you cut calculation time as well as shortening testing and development cycles.
Driving tests In driving tests, BPW analyses the load on frame components: deformation or stress on connecting pieces, gusset plates and crossmembers is recorded using strain gauges and evaluated with the vehicle manufacturer. This means frame and chassis components can be optimally designed prior to the start of volume production.

Service and Distribution / Engineering
Test facility trials In BPW test facility trials, components are subjected to pulsating or alternating forces. Various test programmes can be used for this, such as driving along a test route. As a result, operational strength and component flexibility can be tested under realistic conditions. This reduces the development time of components and modules.
Modular test rig Using the 12-channel modular test rig, BPW can simulate all vertical, transverse and longitudinal forces as well as braking, steering and pitching torques that can act on the running gear during operation. As a result, off-road tracks can be simulated in real time and test track drives can be reduced. Also, the inspections are rendered more reproducible.
Brake calculations BPW prepares EC/ECE brake calculations on the basis of BPW brake cylinders as well as components and designs from other manufacturers. In this way, design tolerances can be exploited sensibly in terms of technology and efficiency. The best possible brake suite and the most effective braking
Turning circle and tilting stability calculations BPW offers you the service of EC-licensed turning circle calculations. This calculation is accepted for the vehicle registration and therefore replaces the practical demonstration in almost all cases. Also, the planned vehicle will comply with statutory provisions right from the start. Since July 2003, the rollover resistance of hazchem vehicles will have to be demonstrated as part of the registration process. An acceleration at right angles of 0.4 g is demanded. This has to be confirmed mathematically or using the tilting test. BPW offers you a mathematical check of compliance with this requirement. It is performed in accordance with ECE regulation no. 111, appendix 4. As a result, the costly tilting test can be avoided. 99

The BPW type plate. Your axle‘s identity document. Every BPW axle has a type plate. It is affixed on the centre of the axle beam, facing to the rear of the vehicle. The information on the type plate enables you to order replacements for wearing parts at any time or – after an accident, for instance – the entire axle.

With BPW, everything is in the right place. This means things that belong together fit together. In drum braked axles from BPW, the air cylinder brackets are welded onto the axle beam. They are used for accommodating diaphragm and spring-type cylinders. The offset hole pattern of the BPW air cylinder bracket permits optimum positioning of the brake cylinder for any lever length. In addition, the air cylinder brackets have marks for additional hole patterns when using small brake cylinders with narrower stud spacings. Dirt, water and snow can escape through a gap between the air cylinder bracket and axle beam.

BPW makes it easy for you. Air suspension installation exactly according to plan. BPW supplies the air installation kit and the corresponding installation diagram for the particular application. The installation diagrams show the valves in what is referred to as the ISO view. The letters and numbers of the valves printed inside boxes on the installation diagrams are identical to the markings on the valves themselves. That makes installation very straightforward. BPW‘s warranty will be invalidated if installation is performed incorrectly by third parties.
Example for air suspension installation: Tri-axle suspension, without lifting and lowering, with axle lift device and LL self-steering axle.

Technical Data / Air suspension / Air suspension installation
The air suspension valve is the heart of the air suspension
axle in tri-axle suspension systems or of the rear axle in tan-
installation. It controls the air bag pressure according to the
dem axle suspension systems. In special cases (e.g. axle lift

Stroke limiting catch straps
Frame attachment
Direction of travel
The valve lever is horizontal in the driving position. It is moved downwards for a functional check. The air now flows out into the atmosphere via the vent flap. However, the valve shaft must be turned through 180° if air gets into the bellows. The valve lever must be installed the other way round for this. The ride height must be set on level ground by moving the articulated rod in the rubber joints and adjusting on the lock nuts.
Axle centre
Direction of travel
Rapid venting In vehicles whose payloads are unloaded rapidly, e.g. tippers, container vehicles, steel strip vehicles, etc., stroke limiting is required in the form of catch straps or rapid venting of the air bags. 1. Stroke limiting is performed using an air suspension valve with integrated shut-off or by a separate shut-off valve. The shut-off valve is bolted onto the vehicle frame and is connected to the axle by means of a return spring hooked onto the draw pin. Once the maximum stroke height has been reached, the air supply to the air bags is blocked thereby limiting the stroke. 2. Stroke limiting can also be performed using catch straps. When installing, make sure the catch strap does not chafe on the axle beam. Crane, rail or ship transport In vehicles for crane, rail or ship transport, BPW recommends air bags with a split piston – the Combi Airbag II system. No stroke limiting is required when the combination air bag is used, providing stroke limiting is not expressly stipulated in the technical documents. Depending on the version, the limiting function is in the shock absorbers in axles with a lifting and lowering device without stroke limiting by shut-off valves or catch straps. The shock absorbers are equipped with a traction stop, however they are not designed for stop forces from approx. 8.5 bar air bag force.

To light axles and reduce costs. With BPW axle light devices. Axle light devices spare tyres in unloaded or low loaded condition and additionally save fuel and therefore cash, thanks to the low rolling resistance along the road. At tandem axle suspensions one axle an be lifted , at tri-axle suspension maximal two axles can be lifted.
With steering axle A „rigid axle/steering axle“ ratio of 1:1 is permitted in vehicles with series LL self-steering axles. As a result, one rigid axle can also be lifted in tri-axle suspension systems. It is advantageous to lift the first suspension axles since this gives greater ground clearance (body lean) and a longer wheelbase – thereby achieving a more stable driving behaviour. The statutory regulations of the German „BO-Kraftkreis“ – defining a turning corridor within which the vehicle must stay when driving in a circle – this must be adhered to! Control Lifting axles are controlled either electro-pneumatically (electric switch), with manual pneumatic control (hand-operated valve) or automatically (compact valve). The overload protection demanded in the legislation is taken into account in the BPW installation kit.

upward travel of approx. 100 mm. A working cylinder can be installed on the air suspension valve if it is not possible to set the ride height for the minimum upward travel.
